best rca cable for deep controlled bass

Sure, a lot of equipment could put out more that it's designed for, but this is short term only. Audiophiles want their amps to give the real power(true watts RMS), both channels driven,20 to 20,000 hz, on a continuous basis. Now that these companies have found ways to use figures such as at 1khz, or whatever else they can to give you a phony rating. Here is an Onkyo receiver that can make one think it will give 135 watts a channel. But the test results show it is far from it. And they only tested it at 1khz, not at 20 to 20,000 hz. Sure an easy test, but failed. Links for this Onkyo.[http://www.us.onkyo.com/model.cfm?m=TX-NR1008&class=Receiver&p=f][http://www.soundandvisionmag.com/content/onkyo-tx-nr1008-av-receiver]

In reference to your second question, one would assume you know the basics, before getting into high tech talk.

READ THE STEREOPHILE REPORT! They tested it according to FTC requirements--one hour 1/3-power burn-in, testing from 20-20KHz continuous power output both channels driven. It measured 110 wpc into 8 ohms and 175 wpc into 4 ohms. What part of that don't you understand? Who cares what the Onkyo specs say when a 3rd party put it on the test bench and tested strictly according to the FTC rules?

In reference to my second question, it's not an issue of "tech talk," it's basic forum courtesy to stick to the OP's subject and not hijack his thread about interconnects by bringing in a 3-year-old post about an amplifier.

Defining clipping as 1% THD, the A-9555 comfortably exceeded its rated power, clipping at 110Wpc into 8 ohms (20.4dBW), 175Wpc into 4 ohms (19.4dBW), and, with one channel driven rather than two, 245W into 2 ohms (17.9dBW) (footnote 1). There is a peculiar rise in the A-9555's THD+N percentage when the output reaches a few watts;

I can read. They pre-conditioned it at one third its rated power. Its rated power is at 1khz, not 20-20,000 hz hz. I only read that they tested it at the way they rated it, for
1 khz. Onkyo themselves say 85 watts at 1khz. Major difference. Don't understand? Apparently not. That's the problem. FWIW, that *at 1 khz* is one of the loopholes. Who listens to 1 khz only? And clipping? You I guess. Onkyo 1khz specs. LOL.

PURIST great everything.

One of the best interconnects I have found for deep, tight, controlled bass is XLO signature. Back in the day they were highly rated by Stereophile and TAS, Then it was the "Signature 1.1" The current version is 3.1. They are unshielded, but most of the time that is not an issue. The Kimber Hero is also good for bass, but not in the same league as the XLO, but it depends on what you want to spend.
Here is an audiogon thread on the 1.1
